Comment(by hesselink):

 Would you say that this is a bug in happstack then, or just something
 users should be aware of? Because this is a hard to debug problem
 (profiling for example doesn't point you to the right place), and it would
 be nice if we could change something to prevent others from running into
 this in the future.
